Parse(ReadOnlySpan<Char>, IFormatProvider)

Converts the representation of a number, contained in the specified read-only span of characters to its BigRational equivalent.

Declaration

public static BigRational Parse(ReadOnlySpan<char> value, IFormatProvider provider = null)

Parameters

Type	Name	Description
System.ReadOnlySpan<System.Char>	value	A read-only span of characters that contains the number to convert.
System.IFormatProvider	provider	An object that provides culture-specific formatting information about value.

Returns

Type	Description
BigRational	A value that is equivalent to the number specified in the value parameter.

Remarks

Like System.Double.Parse(System.String) but with unlimited number of digits.
Additional: Converts Fraction notation like "1/3" or "-123/456"
Additional: Converts Repetions like "0.'3", see: ToString(String, IFormatProvider).
Ignores spaces, underscores (_) leading dots (…)

Parse(String, NumberStyles, IFormatProvider)
